Description

Air handling unit with assembly means {DEVICE FOR TREATING AIR WITH ASSEMBLY MEANS}

The present invention relates in particular to an air treatment device for heating, ventilation and / or air conditioning equipment for a cockpit of an automobile. The present invention relates in particular to the assembly means of the air treatment apparatus.

Apparatuses for treating air using a volatile treatment agent contained in the interior of a permeable container for gradually diffusing the dentifrice through a container wall on a predetermined wall are known. Such treatments are, for example, fungicides, antibiotics or perfume treatments. Such a device is disclosed in French patent application FR-A-2 879 103.

This configuration treats air with a volatile treatment contained within the permeable container that provides a satisfactory, safe, and permanent diffusion of the treatment, thereby optimizing the surface at which the treatment spreads across the container and ultimately reducing general volume. It can suggest a device to.

Nevertheless, such devices are generally incorporated into air filters for the cockpit of a motor vehicle having a peripheral edge that retains the filtration medium installed in the heating, ventilation and / or air conditioning system. However, it may be desirable to propose a treatment device for a vehicle cockpit that is arranged in various ways to treat a particular area of the vehicle. This arrangement is especially known from French patent application FR-A-2 872 455.

In addition, these devices are adapted to be modified as necessary to ensure permanence in the treatment of the air flow. Thus, incorporating the device into an air filter requires extraction of the air filter to ensure its maintenance. This operation damages the filter media or the filter structure, which can render the filter ineffective while reinstalling it inside the heating, ventilation and / or air conditioning system. Likewise, the air filter must be replaced periodically. Therefore, the air treatment device must remove the used air filter before it is reassembled to a new air filter. This constitutes an additional maintenance step that can cause deterioration of the air treatment device and reduce its efficiency. It is necessary to separate these two elements in order to be able to independently repair these air treatment devices and air filters.

In the end, known air treatment devices are additional and / or optional equipment. Thus, it should be possible to mount to any type of heating, ventilation and / or air conditioning system without compromising its function. In particular, the installation of such a device should not harm the general volume of the device and should not increase the charge loss in the air circuit of the device.

It is an object of the present invention to solve the above disadvantages.

According to a preferred embodiment, the slide forms a dovetail assembly means with the groove substantially in the form of a ladder call.

Alternatively, the assembly means further comprises a rib and at least one arm cooperating with the lip. Thus, cooperation between the lip and the arm is realized with pins crossing the boring implemented in the lip and the arm.

According to this embodiment, the device is assembled by translating the rails in grooves parallel or perpendicular to the wall.

Another object of the invention is to propose a device which is assembled by the rotation of the container with respect to the wall. For this purpose, the fastening means can ensure the maintenance of the device against the wall. In particular, the assembling means is assembled on the intermediate member cooperating with the container.

Preferably, the assembly means traverses the opening embodied in the wall 10 and cooperates with said opening by means of a "plug" type assembly.

In particular, it is preferable that the assembly means have sealing means.

The present invention also provides an air flow treatment facility comprising at least one air flow circulation circuit that defines a space in which an air flow traversed by at least one wall having assembly means enabling assembly of the air flow treatment device. The purpose.

It is arranged on one wall of the aerator which can diffuse the air flow.

According to various embodiments, the wall preferably has an opening that can access the air treatment device.

According to the present invention, the flow treatment device can be detachably and easily assembled in the space in which the air flow traverses. On the other hand, the present invention provides the possibility of arbitrarily installing an air flow treatment device in a space traversed by an air flow which is not initially intended to receive the air flow treatment device.

1 and 2, an air treatment apparatus further comprising a permeable container 1 comprising a volatile treatment agent is intended for the treatment of air. The treating agent is conditioned by being absorbed into the spongy tacky body 2 charged inside the permeable container 1, the volume of the permeable container 1 being at least partially such as in the internal cavity of the container 1. Occupies almost all of the volume of the chamber 3 formed thereby. More particularly, the spongy tacky body 2 occupies the volume of the chamber 3 except for the thin air layer provided between the cavernous tacky body 2 and the chamber 3. These devices aim at facilitating introduction of the spongy tacky body 2 inside the chamber 3 and provide a space between the chamber 3 and the cavernous tacky body 2 to further promote the release of the treatment agent. do.

The container 1 is equipped with a cap 4 for closing the chamber 3 in which the container 1 is housed as an internal facility. This cap 4 is forcefully fixed inside the container 1 if the device is consumable.

The container 1 is formed of a rigid and permeable plastic material. According to a particular embodiment, the thickness Ep of the container 1 is 0.9 mm for a total surface of 4200 mm ² ± 10% at a constant temperature of about 40 ° C. to diffuse 45 mg of the treatment agent over a year. It is thought to be ± 20%.

The volume of the chamber 3 should be considered on the basis of the volume of the tacky body 2, these volumes being substantially the same except for the space desired to be provided between the inner wall of the container 1 and the tacky body 2. Will understand.

The permeable container 1 is generally cylindrical. According to a preferred embodiment, the outer wall 6 of the container 1 has a flat shell 8. The flat shell 8 ensures the role of the adjusting pin for installation of the permeable container 1 in the operating environment, in particular in heating, ventilation and / or air conditioning devices. The flat shell 8 also provides a support surface or an assembly surface for all holding devices of the container 1.

3 and 4 show first and second retaining alternative means, respectively. According to the embodiment shown in FIG. 3, the flat lumber 8 provided by the container 1 serves to support the retaining rail of the container 1 on the wall 10. The rail is T-shaped and has an edge 12 and a slide 14 whose length is greater than the length of the edge 12. The edge 12 can secure the connection between the flat horn 8 of the container 1 and the slide 14. In a particular manner, the edge 12 and the slide 14 have a rectangular cross section. Thus, the container 1, the edge 12 and the slide 14 constitute one unit. In particular, this one unit comes from assembly and is embodied in plastic.

However, considering the possible properties of the container, this unit can be implemented in a plurality of assembly steps. In the first step, it is conceivable to assemble the container 1 of permeable plastic. In the second step, the edge 12 and the slide 14 are connected to the rigid plastic, in particular the polypropylene container 1, by assembly.

In order to ensure that the container 1 is assembled to the wall 10, the slide 14 is inserted into the groove 16 provided in the wall 10. More specifically, the wall 10 has two appendages 18 and 20 of the 'L' shape. According to a preferred embodiment, the appendages 18 and 20 are arranged symmetrically with respect to the plane of symmetry P of the container 1 arranged perpendicularly to the wall 10. According to this arrangement, the groove 16 can be defined. In addition, the two appendages 18 and 20 are spaced apart such that a residual space 22 occurs between them. The length of the remaining space 22 is equal to the length of the edge 12 and the length of the slide 14 is smaller than the length of the groove 16 leaving a clearance 24. In addition, the height of the slide 14 is equal to or smaller than the height of the groove 16. This dimension definition ensures sliding against the wall 10 of the unit constituted by the container 1, the edge 12 and the slide 14, which is the most adjustable and can limit the insertion load.

Alternatively, it is conceivable that the remaining space 22 is smaller than the length of the edge 12 and that the length of the slide 14 is the same as the length of the groove 16.

The assembly of the unit consisting of the container 1, the edge 12 and the slide 14 on the wall 10 is parallel to the wall 10 and by the insertion of the slide 14 into the groove 16 and the container ( It carries out by translating a unit to the direction contained in the symmetry plane P of 1).

The container 1 is loaded with an air treatment agent for controlling the environment of the treatment device, and the cylindrical ring 30 is preferably provided with an opening around it so that the treatment agent can be diffused. Alternatively, it is conceivable that the ring 30 acts in a grip manner to provide space for the air stream to contact the container 1 without completely tightening the container 1. Another variant consists in implementing the ring 30 from a permeable plastic material similar to the container 1.

Assembly of the air treatment device is performed by inserting the container into the ring 30 such that the ring 30 tightens the container 1. Advantageously, the ring 30 further has a flat horn 8 on its lower surface which is in surface contact with the flat horn 8 present on the outer wall 6 of the container 1. Thus, an adjustment pin is implemented for assembly. The assembly on the wall 10 is then carried out in the same manner as described above.

3 and 4 show slides 14 and 34 of the 'T' shape. Modifications to these embodiments consist of an 'L'-shaped slide that fits into a complementary groove.

A third embodiment is shown in FIG. 5, in which the assembly means between the container 1 and the wall 10 is realized by a substantially trapezoidal slide 40. Thus, the slide 40 is connected to the container 1 by the edge 46. Edge 46 and slide 40 define a container 1 retaining rail on wall 10.

According to an embodiment, the length of the edge 46 is greater than the length of the edges 12 and 32 of the embodiment disclosed above. Thus, the edge 46 is dimensioned to cover the entire flat hornpiece present around the outer periphery of the container 1. In a variant embodiment, however, it is possible to connect the slide 40 to the container 1 via the flat horn 8 with smaller edge dimensions.

By the complementary form, the slide 40 is inserted into a substantially trapezoidal groove 16 '. The groove 16 'is realized by two appendages 42 and 44 with sloped edges 48 and 50, respectively. In a specially adapted manner, the accessories 42 and 44 are planes of symmetry of the container 1, which are arranged perpendicular to the wall 10, such as the accessories 18 and 20 of the disclosed embodiments in connection with FIGS. 3 and 4. It is arranged symmetrically with respect to (P) and spaced apart so that a residual space is formed therebetween.

Perforations 66a, 66b and 70 are arranged defining a transverse passageway extending to both sides of arms 62 and 64. To keep the unit in place, the pins 68 are inserted into the transverse passages extending to both sides of the arms 62 and 64.

When there are a plurality of perforations arranged along the length of the arms 62 and 64 and the lip 60, a plurality of pins are assembled in each hole.

At a minimum, at least two pins should be arranged in order to properly hold the unit consisting of the container 1 and the arms 62 and 64 on the wall 10.

Preferably, the diameter of the pin 68 is equal to or slightly larger than the inner diameter of the perforation 70 of the lip 60 and the perforations 66a and 66b of the arms 62 and 64. In this dimensional configuration, pin 68 is assembled without gaps or with force to ensure retention of the assembly means consisting of lip 60 and arms 62 and 64.

The fifth embodiment is shown in FIG. The maintenance aspect of this embodiment is the same as that of FIGS. This relates to installation by translational movement.

The flat horn 8 of the container 1 of FIG. 7 has an edge 84 connecting the container 1 to a slide 86 in the form of an 'O' shaped cylindrically according to this embodiment.
